Description and Introduction

Low Voltage, Level Shifting Hot Swappable 2-Wire Bus Buffer with Stuck Bus Recovery The **LTC4308CDD#PBF** is manufactured by **Linear Technology (now part of Analog Devices)**.  

### **Specifications:**  
- **Type:** Hot Swappable 2-Wire Bus Buffer  
- **Package:** 8-Lead DFN (3mm x 3mm)  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **I²C Bus Capacitance Buffering:** Up to 400pF  
- **Low Offset Voltage:** 30mV (max)  
- **High Noise Margin:** 0.3V (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Enable Pin:** Allows bus isolation  
- **Rise Time Accelerators:** Improves bus speed  

### **Descriptions:**  
The LTC4308CDD#PBF is a hot-swappable I²C/SMBus buffer that allows insertion and removal of cards without disturbing the data and clock lines. It provides bidirectional buffering, maintaining bus integrity during live board insertion.  

### **Features:**  
- **Prevents Data Corruption:** During live insertion/removal  
- **Level Shifting:** Supports mixed-voltage buses (2.7V to 5.5V)  
- **Stuck Bus Recovery:** Automatically releases bus if stuck low  
- **Low Quiescent Current:** 1.5mA (typical)  
- **Compatible with I²C and SMBus Standards**  
- **Short-Circuit Protection:** On SDA and SCL lines  

This device is commonly used in applications requiring hot-swap capability, such as servers, telecom equipment, and industrial systems.
